You have told the system to use sendmail, not postfix.  See the handbook for how to configure mailer.conf for postfix and then configure postfix.  See the postix documentation on the web for instructions.  if you have issues, there is a how to get help section in the documentation.  Follow that and use the postfix maillist.
